尝试将获取请求从控制器模块导入到主应用程序时出现错误。 （类型错误：无法读取未定义的正确“获取”）

Question

This is my index.js file in my ./home directory:

var express = require('express');
var control = require('./controllers/todoController');
var app = express();

//set up template engine

app.set('view engine', 'ejs');

//static files
app.use(express.static('./public'));

//fire controllers

control();

//listen to port
app.listen(3000);
console.log('You are listening to port 3000');

This is my todoController.js file in my ./home/controllers directory:

module.exports =function(app){
  app.get('/quiz', function(req, res){
  res.render('quiz');
});
};

The error that is shown is:

TypeError : cannot read property 'get' of undefined

Answer 1

You must give your app to controller as parameter

Try this in your index.js file

//fire controllers

control(app);

Answer 2

Use the router module of expressjs

 const express = require('express'); const router = express.Router(); /* GET home page. */ router.get('/', function(req, res, next) { var token = req.body.token('token'); if(!token) { res.render('error', { 'message': "You must indicate a Token" }); } }); module.exports = router; 

Then, just import it on your app.js main file :

app.use('/', tokenHandler);
